airlessness
Absence of atmosphere
Airlessness is the state of having no air or inadequate ventilation.
A room's airlessness makes it stuffy and oppressive: The airlessness of the basement was suffocating.
The word extends to atmospheres lacking oxygen entirely—the airlessness of space or the lunar surface.
Figuratively, airlessness can describe environments that feel stifling or creatively dead.
